Abstract
Background: Stroke causes severe impairments in mobility, balance, and quality of life, making it the leading cause of disability globally. New research indicates that high-intensity interval training (HIIT) may benefit stroke patients more. Objective: To determine the effects of high-intensity interval training on mobility and fitness outcomes in stroke. Methods: A single-blinded, randomized controlled study was carried out on n=44 ambulatory stroke survivors between the ages of 45 and 65 years. The participants were randomly assigned to group A (n=22) received conventional physiotherapy (CPT). While Group B received HIIT in addition to conventional physiotherapy. The Berg Balance Scale (BBS), Heart Rate Recovery (HRR), Functional Ambulation Categories (FAC), Stroke-Specific Quality of Life (SS-QOL), Timed Up and Go (TUG) test, and the 6-Minute Walk Test (6MWT) were the outcome measures. At baseline, six weeks, and twelve weeks, assessments were carried out. Results: The HIIT group had significantly improved mobility, balance, and cardiovascular fitness. In the 6MWT (p<0.001), BBS (p<0.001), FAC (p=0.002,), insignificant p-value in HRR (p=0.93, ηp²=0.00), SS-QOL (p=0.01, ηp²=0.16), and TUG tests (p=0.01, ηp²=0.16), and hence was better (p < 0.05) in all variables except FAC (0.48). Conclusion: High-intensity interval Training significantly improves walking capacity, balance, cardiovascular recovery, and quality of life in stroke survivors when combined with conventional standard physiotherapy interventions, as compared to conventional physiotherapy alone.
